How to Combine Personal Leave With a TDY House Stay (Without Breaking DTS or Per Diem)

Service members frequently want to add personal leave before or after a TDY. The desire is practical. A multi-week or multi-month assignment already requires travel. Extending the stay by a few days for family, rest, or local travel reduces total trips and cost. When the lodging is a non-conventional house instead of a hotel, the question becomes sharper. Can the same property be used for both the official TDY period and the personal leave days without creating DTS or per diem problems?

The short answer is yes, when the official and personal periods are clearly separated and documented. The Joint Travel Regulations allow personal leave in connection with TDY. Reimbursement, however, is limited to the authorized TDY days. Lodging costs, per diem, and Government Travel Card charges that fall outside the official orders are the traveler’s responsibility. A house stay does not change that rule. It does make the documentation cleaner when the booking is handled as a single, transparent reservation rather than two separate consumer bookings.

How Leave and TDY Lodging Interact

Official TDY lodging is reimbursable at the applicable per diem rate for the authorized days. Personal leave days are not. If a traveler arrives three days early or stays four days after the TDY ends, those extra nights are personal. The unit cannot reimburse them, and they should not appear on the DTS voucher as official lodging.

When the lodging is a hotel, the traveler often simply checks out and checks back in, or pays the personal nights on a personal card. With a house, the more efficient path is to keep the same property. The booking can cover the full calendar period. The invoice or supporting documentation then identifies which nights fall under the TDY orders and which nights are personal. Only the TDY nights are claimed. The personal nights are paid by the traveler and excluded from the voucher.

This approach works under the JTR when three conditions are met. First, the orders clearly state the official TDY dates. Second, the lodging documentation separates official and personal nights. Third, no government funds or GTC charges are used for the personal portion. Units that already use non-conventional lodging for mission reasons can apply the same separation to leave extensions without creating a new compliance path.

Documenting the Stay in DTS

Clear documentation prevents the most common problems. The trip request or booking confirmation should list the full stay dates. The invoice or itemized statement should show the nightly rate and then identify the subset of nights that match the TDY orders. A short note or attached spreadsheet that states “TDY nights: [dates], personal nights: [dates], traveler paid personal nights separately” is usually sufficient.

In DTS the traveler claims only the official nights. The receipt uploaded to the voucher should match the amount claimed. If the full house invoice covers both periods, the traveler can annotate the receipt or provide a second document that isolates the TDY portion. Finance offices review for consistency between orders, claimed dates, and supporting receipts. When those three items align, the personal leave days do not create a reimbursement delay.

Government Travel Card use follows the same split. The GTC should be charged only for the reimbursable TDY nights. Personal nights are paid with a personal card or other personal funds. Mixing the two on a single GTC charge creates reconciliation work and can trigger questions during voucher review. Keeping the payment methods separate is the simplest way to stay inside the rules.

Practical Steps for Planners and Travelers

Start with the trip request. Include both the official TDY dates and the requested personal leave dates. Note that the traveler intends to remain in the same property for the personal days and will pay those nights personally. This allows the lodging provider to prepare one reservation and one clear cost breakdown instead of forcing two separate bookings.

Confirm the nightly rate early. Per diem caps still apply to the official portion. If the house rate is at or below the lodging portion of per diem for the TDY nights, reimbursement is straightforward. If the rate exceeds the cap on any official night, the traveler is responsible for the difference on those nights as well. The personal nights remain entirely the traveler’s cost regardless of rate.

Request an itemized document before the stay ends. Most units need the final breakdown before the traveler submits the voucher. Having the TDY nights, personal nights, and payment method already separated reduces back-and-forth with finance. Travelers who add leave after the original booking should notify the lodging provider and their planner as soon as the leave is approved so the documentation can be updated before check-out.

Common Issues and How to Avoid Them

The most frequent problem is claiming every night on the DTS voucher because the invoice shows one total. Finance then rejects or reduces the claim, and the traveler must amend the voucher. Separating the nights on the supporting documents before submission prevents this.

A second issue occurs when the GTC is used for the entire stay. The personal portion must be paid back immediately or the charge becomes an improper use of the card. Paying personal nights with a personal card from the start eliminates the problem.

A third issue arises when the leave dates change after the property is booked. If the official TDY dates stay the same, the documentation simply updates the personal nights. If the official dates also move, the trip request and orders should be amended first so the reimbursable window remains accurate.

Why Houses Make the Combination Easier

A hotel stay often requires a new reservation or a rate change when leave is added. A house booked as non-conventional lodging can remain under one agreement for the full period. The property does not turn over between the TDY and the personal days. Utilities, parking, and kitchen access continue without interruption. For the traveler this is convenient. For the unit it is administratively simple once the nights are labeled correctly.

Because the booking is made in the company name rather than the traveler’s personal name, there is no personal lease that extends into the leave period. The official portion remains a standard TDY lodging expense. The personal portion is a private transaction between the traveler and the provider. This structure keeps the JTR and DTS path clean while still allowing the traveler to stay in the same house.

Frequently Asked Questions

Can I be reimbursed for lodging on personal leave days attached to TDY?


No. Reimbursement is limited to the authorized TDY dates on the orders. Personal leave nights are the traveler’s responsibility.

Do I need separate reservations for the TDY and the leave?


Not if the documentation clearly separates the nights and payment methods. One reservation with an itemized breakdown is usually cleaner.

Can I use my Government Travel Card for the personal nights?


No. The GTC should be used only for reimbursable official expenses. Personal nights should be paid with personal funds.

What if my leave is approved after the house is already booked?


Notify the lodging provider and update the documentation. As long as the official TDY dates do not change, the reimbursable portion stays the same.

Does this work the same way for a team house and a solo traveler?


Yes. The rule is based on orders and dates, not on the number of travelers. Each person’s official nights must still match their orders.

Next Step

Combining personal leave with a TDY house stay is allowed and practical when the official and personal periods are kept separate in both payment and documentation. The same non-conventional lodging that supports the mission during the TDY can continue through the leave days without creating a new compliance problem.

If you are planning a TDY that includes personal leave before or after the official dates, include both sets of dates in the trip request at www.9lineagency.com. The courses of action can be built so the house covers the full period and the documentation already separates the reimbursable nights from the personal nights. Your mission dates stay clean in DTS. The extra days stay simple for the traveler.
